- description
- Guide for shortening any URL via public web services. Use whenever the user asks to shorten, abbreviate, or create a shareable link from a long URL. This skill does NOT execute HTTP itself — it instructs the agent to invoke the existing http_fetch tool, which has a different network fingerprint that bypasses the anti-bot filters that block the on-device QuickJS fetch.

URL Shortener (guide)
This skill is instructions-only. It does not run any code on the device. When the user asks to shorten a URL, the agent should use the existing http_fetch tool to call one of the public shortener APIs below and then return the response body as the short URL.
Preferred backend: da.gd
GET https://da.gd/s?url=<URL-encoded original URL>
Exactly one call. Response body is the short URL as plain text (no JSON).
Agent procedure
- Extract the original URL from the user's message.
- It must start with http:// or https://. If not, ask the user to provide one.
- URL-encode the original URL (apply
encodeURIComponentto it). - Call
http_fetchwith these parameters:
- url: https://da.gd/s?url=<encoded original> - method: GET
- Take the raw response body, strip surrounding whitespace, and verify it
starts with https://da.gd/. If so, return that as the short URL.
- If the body doesn't match, or the status is not 2xx, fall back to one of
the alternate backends below.
Example
Original:
https://github.com/anthropics/claude-code/tree/main/docs/very/long/pathEncoded:
https%3A%2F%2Fgithub.com%2Fanthropics%2Fclaude-code%2Ftree%2Fmain%2Fdocs%2Fvery%2Flong%2FpathFetch:
http_fetch({ url: "https://da.gd/s?url=https%3A%2F%2Fgithub.com%2Fanthropics%2Fclaude-code%2Ftree%2Fmain%2Fdocs%2Fvery%2Flong%2Fpath", method: "GET" })Expected response body: https://da.gd/XXXXXX
Fallback 1: cleanuri.com
POST https://cleanuri.com/api/v1/shorten
method:POSTcontent_type:application/x-www-form-urlencodedbody:url=<URL-encoded original URL>
Response is JSON: {"result_url": "https://cleanuri.com/XXXXXX"}. Parse and return result_url.
Fallback 2: tinyurl.com (unreliable)
GET https://tinyurl.com/api-create.php?url=<URL-encoded original URL>
Response body is plain text like https://tinyurl.com/XXXXXX. Some clients get bot-detected and receive a "deprecated preview" placeholder — if the response body lies outside the https://tinyurl.com/ domain or redirects to tinyurl.com/preview/deprecated, treat it as a failure and move on.
Notes for the agent
- Always verify the final short URL's domain matches the backend's own
domain before returning it.
- If all three backends fail, tell the user honestly — do not fabricate a
short URL.
- The user cares about reaching the original URL through the short link.
Do not silently substitute a different destination.
